چکیده
یکی از مهم­ترین نگرانی­های جهان امروز، حجم قابل توجهی از تجمع زباله­ها­ی مربوط به پلیمر­های سنتزی مورد استفاده در بسته­بندی موادغذایی می­باشند. بنابراین فیلم­های خوراکی زیست­تخریب­پذیر بهترین جایگزین برای پلاستیک­ها و پلیمر­های سنتزی هستند. به همین­منظور در این پژوهش، فیلم­های زیست­تخریب­پذیر زئین ذرت حاوی عصاره برگ زیتون در دو سطح غلظتی 10 و 15 درصد (وزنی/ وزنی)، تولید و خواص فیزیکی، مکانیکی، رنگ­سنجی و ریزساختار بررسی گردید. نتایج آماری نشان داد که اثر تیمار بر خواص فیزیکی، مکانیکی و رنگ­سنجی معنی­دار (p<0.05) بود. نتایج نشان داد با افزودن عصاره 15درصد مقادیر ضخامت و جذب رطوبت نسبت به نمونه شاهد افزایش داشت. همچنین با افزایش درصد عصاره برگ زیتون کاهش قابل توجهی در حلالیت و نفوذپذیری بخار آب در هر سه رطوبت نسبی (33، 50 و 75 درصد) نسبت به نمونه شاهد مشاهده گردید. به­طور­کلی، از نتایج این تحقیق می­توان دریافت که ترکیب کردن عصاره برگ زیتون به پلیمر زئین سبب بهبود برخی ویژگی­های فیزیکی و مکانیکی فیلم خوراکی می­گردد.

چکیده English

Today one of the most important concerns of the world is the significant volume of waste accumulation associated with the synthetic polymers used in food packaging. Therefore, biodegradable edible films are the best alternative for synthetic polymers and plastics. In this study, biodegradable films of corn zein containing two levels of olive leaf extract (10 and 15% w/w) are produced and their physical, mechanical, colorimetric and micro straucture properties were investigated. The results showed that the effect of treatment on physical, mechanical and colorimetric properties was significant (p <0.05). The results showed that by adding 15% extract, the thickness and moisture absorption increased compared to the control sample. Also, by increasing the percentage of olive leaf extract, there was a significant decrease in solubility and vapor permeability in all three relative humidity (33, 50 and 75%) compared to the control sample. In conclusion, it can be concluded from the results of this study that the combination of olive leaf extract with polymeric zein improves some physical and mechanical properties of edible film
